Specification of Letters Patent.

Patented April 27, 1809.

Application filed July 6, 1905. Serial No. 268,486.

To all whom it may concern:

Be it known that I, LEWIS T. Houenron, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented anew and useful Spool-Head, of which the following is a specification.

This invention relates to that class of spools which are employed in spooling frames or for similar urposes.

The especia object of this invention is to provide a light, strong and nearly indcstructible spool which can be manufactured and sold at a cost of little if any in excess of the spools ordinarily used.

To this end, this invention consists of the spool as an article of manufacture, and of the combinations of parts therein as hereinafter described and more particularly pointed out in the claims at the end of this specification.

In the accompanying two sheets of drawings, Figure 1 is a side view partly broken.

away of a spool constructed according to this invention. Fig. 2 is a fragmentary view of the inside of one of the spool-heads. Fig. 3 is a perspective view of one end of the body of the spool. Fig. 4 is a fragmentary perspective view of the tubular center rivet. Fig. 5 is a fragmentary view of the outside of one of the spool heads. Fig. 6 is a perspective view of one of the center washers over which the end of the center tube is riveted. Fig. 7 is a fragmentary view partly in heads illustrated in Fig. 7, and Fig.

section illustrating a modified construction. Fig.8 is a fragmentary end View of the spoolbody shown in Fig. 7. Fig. 9 is a fragmentary view of the inside of one of the spool 10 is a fragmentary view of the outside of one of the spool heads illustrated in Fig. 7.

In order to withstand the rough usage to which spools are subjected in cotton mills it is essential that the spools be stro g, light, and at the same time they must be of 00111- paratively inexpensive construction. In the use of spools of this class the spools are liable to be damaged either by the bending or breaking of the spool head, or by the shearing off of the fastening at the center of the spool head.

In the S ools now ordinarily employed the spool-hea are fastened simply by being butted against the end of the body of the spool, and in such constructions all concussions or blows upon the spool-heads are transmitted direct y to the fastening which holds the spool-head from being pulled off the end of tLG spool.

The weakening of the fastening of the spool heads by repeated concusslons due to the dropping of the spools or from other causes fre uently causes the s oolheads to become oose and shackly, I ave found that this can be overcome by providing the spool heads with socketsffor receiving the projeetin ends of the spool body, and in order to 0 this without weakening the spool-head, I have found it desirable to provide the spool-head with radial ribs or corrugations which extend closer tothe center of the spool-head than the circumference of the spool body, and which may extend out as near the perimeter of the spool head as required. These ribs or corru ations serve to strengthen the spool head w ere it would otherwise be weakened by the formation of the recess or socket for receiving the end of the spool-body.

Referring to the accompanying drawin s for a detail description of two forms of spoo embodying this invention, as shown in Fig.1, 10 designates the tubular body of the spool. The spool-body 10 may be of wood, fiber, cardboard, or any other material of suflicient strength and lightness to be used. At its ends the body ortion of the spool is pro vided with radial notches 11 and 12 for holding the spool heads from turning. The spool heads 13 each consists of a disk which is preferably pressed out of paper, leather-board, or similar light and inexpensive material. Each of the s 001 heads is provided on its inner face wit an annular recess 14, with diametrically 0 posed projections or ribs 15 which fit into t e sockets or notches 11 and 12 of the body of the spool.

In order to strengthen each of the spoolheads 13 the spool-head when pressed out of paper or similar material is provided with a pressed out center art, and with radial ribs 17 which preferab y extend to the outside bead or flange 16 of the s 001 head. These radial ribs serve to strengthen the spool head where it would be otherwise weakened by the formation of the recess on its inner face which receives the spool-head.

The means which I em loy for holding the spool heads in place so t at they cannot be pulled off the end of the spool body comprise a hollow central tube or rlvet 19 and conical end washers 18.

The ends of the tube 19 are turned back and riveted to engage the center washers so as to form a,rigid construction in which the setting of the ends of the sBool-body in recesses in the spool-heads w l overcome the tendency of the spool-heads to workloose by reason of shearing strains upon the center fastening.

In some cases instead of using a tubular spool body and instead of using spool-heads 0 paper or similar material, I may use a sohd wooden spool-body and may use sheet metal disks for the spool-heads. A construction of this character is illustrated in the second sheet of drawings.

The spool illustrated in the second sheet of drawings comprises a wooden spool center 21 having projecting conical ends with radial notches or recesses 22. The spool head 23 consists of a sheet metal disk having a strengthening bead 24 around its outside edge, and a central bent out socket for receiving the end of the s )ool-head. The center of the sheet metal disk is reinforced and strengthened by ribs or corrugations 25 which will stifien and strengthen that part of the disk which otherwise would be weakened by the formation of the bent out socket for the spool-heads. Each spool-head is held from turning by means of inwardly extending radial corrugatlons or proj ections26 which engage the corresponding notches 22 in the ends of the spool-body. The parts are fastened together by a central tube or hollow rivet 27 which is riveted back directly onto the sheetmetal spool-heads without the intervention of an end collar. In this construction as in that previously described, it will be seen that tion of its socket will be reinforced and stifl' ened by the radial ribs; v

1 am aware that changes may be made in the shape and proportions of spools without departing from the scope of my invention as expresse in the claims. I do not wish,

therefore, to be limited to the particular spool which I have herein shown and described, but

What I do claim and desire to secure by Letters Patent of the United States is 1. As an article of manufacture, a spool com irising a cylindrical spool body, spool hem s at the ends thereof, each having an annular recess fitting the end of the spool body, and a radial projection in the recess engaging the end of the s )001 body to keep the parts from turning, t e heads bulging outwardlv at the center thereof, and a rivet passing through the spool and engaging the ulged portions of the two heads to fasten the same in place on the spool body.

.2. As an article of manufacture, a spool com rising a tubular body and pressed out spoo -heads each having an annular recess for receiving the end of the body, said recess and body having a radial projection and socket fitting each other to keep the parts from turning, and means for fastening the parts together comprising end washers and a rivet passing through the spool body and having its ends headed back into the end washers.

3. As an article of manufacture, a spool comprisin a tubular body and pressed out spoo heac s, each having an annular recess for receivin the end of the spool body, said parts being old from turning by a pro ection on one of said parts engaging a corresponding socket in the other, each of said spool heads having a marginal bead and radial ribs strengthening the center part of the spool head in which the recess is formed, and means for fastening the parts together comprising end washers, and a tubular rivet havlng its ends headed back onto the end of the washers.

4. As an article of manufacture, a spool comprising a tubular body and pressed out non-metallic spool heads each having an an-.

nula'r recess for receiving the end of the body, said recess and body havin a radial rojection and socket fitting eac 1 other an extending across and interrupting the recess to keep the parts from turning, and means for fastening the heads together.

In testimonv whereof I have hereunto set mv hand, in the presence of two subscribing witnesses.
